AbstractLess is known about the impact of heart failure (HF) and coronary artery disease (CAD) on motor recovery after cerebral infarction although previous studies have reported that preexisting HF and CAD were associated with increased mortality in stroke patients as well as unfavorable functional outcomes. In this study, we aimed to accurately evaluate the impact of HF and CAD on motor recovery after cerebral infarction by including only patients with corona radiata using diffusion tensor tractography. A total of 110 patients were recruited, and diffusion tensor tractography was performed within 7 to 30 days of infarct onset. Motor function on the affected side was evaluated for each patient using the upper myocardial infarction (MI), lower MI, modified Brunnstrom classification, and the functional ambulation category at the onset of stroke and 6 months after the onset of stroke. The influence of preexisting HF and CAD on the recovery of motor function were analyzed, adjusting for critical factors for motor recovery after stroke, namely the corticospinal tract condition, lesion location, age, and upper and lower MIs at the onset of stroke. No significant difference was found in motor outcomes according to the presence of HF, while poorer outcomes in motor function of the lower extremities and gait ability were observed in patients with CAD compared to patients without CAD. Motor function of the lower extremities and gait ability in cerebral infarct patients with CAD is more impaired than those without CAD.Copyright © 2023 the Author(s).
